That really doesn’t seem to fit with what is known about Abraham. It makes no sense that he’d have anything to do with impure names of God nor be able to confer mystical powers on others.
The idea conveyed is that he gave the power as “gifts” to protect themselves. While the pure tradition/mysticism he gave to Isaac.
While we’re on “what is known about Abraham,” does your church believe he smashed his father’s idols? Or that Nimrod threw him into a fire (which he miraculously survived,) or any of what the Jewish Midrash (commentary) calls the ten trials of Abraham? (Culminating in the binding of Isaac.)
